Claims. 1

This invention relates 'to' to'o-ls' for use by Wat-ch makers and watch repair men, and more particularly, has reference to a device whereby a;roller jewel may be readily positioned in the opening formed in a roller tableof a watch.

Bywa'y' of background, it is pointed out that the roller table of 'a' watchis only a very -srri'a'll component part of the works thereof Especia'll'y is this. soin most "watches presently use, it being well known that'the tendency is"t'c make watches-asflatand as small as possiblewith the result that the various parts thereof are" exceedinglytiny; and are compressed into-a very small area.

In this "connection; eac-nroher' table is formed with a" small opening in which is 'received-"airoller jewel. "It is necessary to insert'the jewel in-the opening and to retainit thereinra'nd then to apply cement, the final step of .theoperationf being the" application of heatther'eto; whereby the-cementaetsto firmly retain the jewel'in theopening; Atiprejsent, 'the'rnethod"customarily employed 'by watch repair Jrnen in iperforining the necessaryfsettin'g and cementing operations? isto use tweezers 'orth'elike' toh'oldtheje'wel, and then insert the .jewel into the opening" inthe roller table:

This method is unusually time" consuming, as will readily be apparent'when the size of'th'e roller table jewel opening and the jewel to be fitted th'ereiritois' considered; Additionally,"itr'is 'dften diflieult to hold the hand steady during theiopera tion, and sometimes the size 'df therpar'ts is" so smalltliat they must be held"close tothefiew through-the openin'gin the renewable;-

A further important objeet of theinvention is to pro-vide adevice of theoharacter' described which will be relatively inexpensive in "construe tiony. whereby the cost of the device-will in a comparativelyshort period of time be"fu'-1ly balanced by savings resulting from the ability of theuser to conserve time in the setting operation; "This is-especiallY 'important where -e large' voldme of repaid-work is ha'ndled.

Still another important obj ecu ofti ief invention is to provide a device of; this' character that is relatively small-insize, compris'ing arnin" number of parts simplyarranged; his bein especially desirable feature in the err-t; W her n already large number of s'r-nall -tools are ndw in use, it being undesirable tohav s;teoicornprismg a large number of easily misplaced 'par-ts With the foregoingand other objects- 1 view which will appear as -the'ele riptien -prboeeiis; the invention consists 1 ofcei tairi novel details or construction and combination of part's ghereinafter more fully described andnointed o claims, it being understoodthat eliainges a be made in'tlie construction and arrangement of parts"withoutdeparting freifi tl'ie spirit of the invention as claimed. 7

Referring to the drawing m detail the ,reference characterfi designatesa'base. This isiprei erably formed of metallic material, and may be hollowed, as shown inFigureB; Thebase :may be: of any suitable: conformation; it beingsnecesear y only that-itpresent'a -steefdysupport for the operation;

The base has a fiat upper surface 6, and-frelii one end thereof there is upward-1y extended a wall a 1. This may conveniently beca's't integ'i 'al With the base} and has flat side surfaces tliafiar disposed perpendicularly tothe upp'er surfabe 'ii of the base 5.

'At' one end, the wall I is-cut "awayas at 8} -th e cutaway portion being ent-way deep; so-" as to present 4 a comparatively wide-and deter) oiieii obviously be cast integral with 3 space at one side of the device, the purpose of which will be described in detail hereinafter.

As best shown in Figure 5, the wall 1 is further formed with a transverse bore 9 that is parallel to the plane of the flat upper surface 6 of the base. The bore 9 is disposed substantially centrally, relative to the upper and lower edges of the wall 1. V

Fitted tightly into the bore 9, so as to be immovably held therein, is a relatively elongated tubular member [0. One end, designated by the reference character H, is flush with the inner side surface of the wall ure 5. From the end II, the tubular member ID is extended laterally away from the wall I. The tubular member ID is formed with an end-toend bore 12, that is open both at the end I I, and at the free end I3 of the tubular member. In diameter, the bore i2 is relatively small, corresponding substantially to the diameter of a roller jewel J that is slidable therethrough. In this connection, roller jewels are, in general, cylindrical or semi-cylindrical. It is essential only that the bore l2 be of such diameter as will permit a roller jewel J to be slidably moved therethrough, without substantial deviation from its path of movement.

Referring to Figure is illustrated that may 13 of the tubular member Hi, this needle being or" such length as will result in its pointed end projecting from the other end i l of the tubular member when it has been inserted therein.

Alternative to the aligning needle I l, a push rod I is also adapted to be inserted in the free end l3 of the tubular member H The push rod 15, as clearly shown in Figure 6, is cylindrical in form, the diameter thereof corresponding substantially to the diameter of the bore 12 of the tubular member. The push rod [5 is provided with the collar 16. Referring particularly to Figures 1 and 2, the push rod is there shown inserted to the maximum extent possible in the bore l2. It is observed when it has been so inserted, the collar it engages the free end l3 of the tubular member I0. When these parts are so engaged, the other end of the push rod projects barely beyond the inner side surface of the wall 1, that is, it moves fully up to, but does not enter, the jewelreceiving opening in a roller table R mounted in close spaced relation to said inner side surface of the wall I. This construction is particularly shown in Figure 5. 7

Intermediate its ends, the tubular member I9 is provided with a cutaway part II, whereby a portion of the bore i2 is exposed. As a result, an open groove is provided that is aligned axially with the bore 12. This permits a jewel J to be placed in the channel or bore l2, preliminary to 7, an aligning needle i l being moved therethrough by means of the push rod l5.

At the other end of the base 5, a rear wall I8 is provided, that extends perpendicularly from the flat upper surface 6 of the base 5. This may the base 5 if desired. 1

Adjacent thelower edge of the rear wall it, and formed parallel thereto, is provided a horizontal slot I!) that extends inwardly from one end of the wall. At the inner end of this horizontal slot, and in communication therewith, is a vertical bore 20, that is threaded to receive a set screw 2|. The set screw 2] has an enlarged head 22 i, as best shown in Fisbe inserted in the free end which engages the upper edge of therear wall l8 1 when the set screw is fully threaded into the bore 20. The head 22 may be knurled as illustrated, and it is preferably additionally formed with handles 23. Thus, the knurled portion may be used for primary adjustment of the set screw, while the handles 23 are operable for making more minute adjustments.

Adjacent theopen end of the horizontal slot I9 the lower end of a vertical threaded bore 24 is in communication therewith, the bore 2e receiving the set screw 25. A small screw 26 is additionally threadable through the wall it, and is adapted to close the open end of the slot $9.

The slot [9 is proportioned to receive a vise for holding the roller table R. A handle 21 is formed with an end-to-end bore, that is threaded at one end to receive the threaded end of a tubular mem ber 28, that constitutes the shank of the vise. The other end of the tubular member 28 is provided with a stationary or rear jaw 29, which, as clearly shown in Figure .8, is formed integrally with a laterally extended extension member 33, which is formed of a heat-conductive material.

Slidable in the tubular member 28 is a rod 3!, having at one end a thin fiat movable jaw 32. The upper edge of the jaw 32 extends slightly above the upper surface of the rear jaw 23, and is formed with one or more semicircular notches 33.

At the other end of the rod 3i there is slidably positioned thereover a small cylindrical block 3%, the threaded end of the rod 3| projecting beyond said block and beyond the handle 2'1. A regulating stud 35 is threaded onto the projecting end. Thus, it is seen that threading of the stud 35 on therod 31 to a desired extent, so as to adjust the distance between the cap of the stud and the adjacent end of the handle 21, will in turn adjust the distance that the jaws 29 and 32 of the vise can be spread apart.

A spring 36 is interposed between the block 3 and the rear end of the tubular member 28, so that after the jaws 29 and 32 are spread apart by pressure applied to the end or cap of the regulating stud 35 the movable jaw 32 is returned to normal position under expanding action of the spring 3t. V

A pin 31 extends rearwardly from the movable jaw 32 through an opening in the jaw 29, where by to hold the jaws in proper alignment at all times.

Other than the particular jaw formation described herein, vises of this type are known in the art, the description provided herein being submitted for the purpose of explaining the operation of the vise as used in conjunction with the remainder of the device.

In operation of my device, the roller table R, which may be of either double type, as illustrated, or the single type, is placed between the jaws of the vise. In the drawings, the roller table has been enlarged considerably, above the proportion which it would ordinarily bear to the device which constitutes the invention, this having been done for the purpose of illustrating more clearly the operation of the device.

In mounting the roller table in the jaws of the vise, the roller table is positioned so that its jewel receiving opening is brought into alignment, as far as possible, with one of the notches 33 in the jaw 32. The lower half of the jewel opening in the roller table R thus constitutes in effect an extension of the semi-circular wall of the notch.

v The vise is then manually moved forwardly, so that the outer face of the jaw 32 engages the rear face of the wall 1. At the same time, the

operator brings "the jewel opening in theroller tablejRinto'rough axial alignment with the open end of'the bore I2.

The needle I4 is then inserted into the other endjl3 of the bore I2 and is extended through the jewel opening in the roller table R. Thus, the'jewel' opening is immediately and" accurately brought into full register with the adjacent end of the bore "I 2.

Obviously, this operation can be performed somewhat differently, if desired. The operation may bebegun by inserting the aligningnee'dle I4 through thefbore I2 soas to project thereb eyond. Then, the vise having the roller table R. mounted therein in the manner previously described, may be moved forwardly so thatthe end of'the needle is received in the jewel'op'en- 111g.

Breferably with the needle I4 still "extended through the jewel opening in the'roller table R, so thatthe opening andthe bore I 2 are not accidentally moved out of register,'the set screw-2I is operated to clamp the vise in position.

The aligning needle I4 is then'removed, and a jewel J is deposited in the groove formed by the cutaway portion I! of the tubular member ID. The push rod I5 is then inserted, and is used'to push'the jewel J through the bore I2, across the notch 33, and into the jewel opening in the roller table R. 'As previously described, the length of the-pushrod I5 is such that it moves only up to thefnearest face of the roller table R whenthe collar lfi'engages the end I3 of the tubular member I0.

As a result of-this construction, it is to be observed that the rear end of the jewel J, that is the endpositioned in the jewel opening of the roller table, will be'exactly flush with the face of the roller table R after the push rod I5 is withdrawn. It is thus placed in proper position for the necessary cementing operation.

The jewel having been set, the set screw 2| is threaded out of engagement with the shank 28 of the vise, and the vise is slidably moved toward the open end of the slot I9. The vise is positioned below the set screw 25, which is threaded against the vise to clamp it in position again.

In this position, the extension 30 of the jaw 29 projects laterally beyond the base 5, and the jewel J, positioned in the jewel opening of the roller table, is exposed for cementing operations by provision of the cutaway portion 8 of the wall I. Cement is applied, whereupon a jewelers lamp or the like is positioned to apply heat to the extension 30. The application of the heat results in a completion of the mounting of the jewel in the roller table.

The small screw 26 cooperates with the set screw 25, to hold the vise in proper position for the cementing and heating steps. By threading of the screw 26 to close the slot I 9, all possibility of the vise slipping out of the slot is removed.

The advantages of a device constructed in accordance with the invention are believed to be obvious, and need not be dwelt upon other than to state that the device removes the necessity of setting a roller jewel by means of the time-consuming and troublesome method now employed.
